Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An apparatus for determining whether a set role of a terminal in a network is suitable based on a capability of the terminal, comprising: a calculation unit which calculates a capability value of the terminal; a determination unit which determines, without considering capabilities and roles of other terminals of the network, whether the set role of the terminal, which is previously set, is suitable based on the calculated capability value; and a setting unit which manages information regarding the set role in the terminal, wherein at least one of the calculation unit, the determination unit, and the setting unit is implemented as a hardware component, wherein the previously set role of the terminal is previously set in the terminal, wherein when the determination unit determines that the set role of the terminal is not suitable based on the calculated capability value, the terminal determines, without considering capabilities and roles of other terminals of the network, to change the set role, and wherein the apparatus is a super terminal or a leaf terminal.
An apparatus, acting as either a super terminal or a leaf terminal in a network, autonomously determines if its current role (either super terminal or leaf terminal) is suitable based solely on its own capabilities. It includes: a calculation unit that calculates a capability value of the terminal; a determination unit that determines, without considering other terminals, if the pre-existing role assignment is suitable based on this capability value; and a setting unit that manages the terminal's role information. If the determination unit finds the current role unsuitable, the terminal autonomously decides to change its role without considering the other terminals in the network. The apparatus is implemented using hardware components.
2. The apparatus of claim 1 , wherein information used in calculating the capability value comprises network performance, remaining battery power, and usability of resource.
The apparatus described in the previous claim calculates the capability value of the terminal considering factors like network performance, remaining battery power, and availability/usability of resources on the terminal. This information is used to decide if the current super terminal or leaf terminal role is appropriate for the device.
3. The apparatus of claim 1 further comprising a controller which controls the terminal to have a supernode role or a leaf node role based on the information regarding the set role managed by the setting unit.
The apparatus described in the first claim further includes a controller which manages whether the terminal functions as a supernode or a leaf node. This decision is based on the role information managed by the setting unit, which is determined by the terminal's calculated capability value. The controller dynamically switches the terminal's role based on its current suitability for either role.
4. The apparatus of claim 3 , wherein the terminal is a first terminal and if the set role in the first terminal is changed from a supernode into a leaf node, the controller searches for a second terminal, and transmits reference information for a leaf terminal stored in the first terminal, to the second terminal.
In the apparatus described with the controller in claim 3, if a first terminal's role changes from supernode to leaf node, the controller searches for a second terminal in the network and transfers leaf terminal reference information stored on the first terminal to the second terminal. This ensures the network maintains its functionality when a supernode transitions to a leaf node. The reference information is necessary for the second terminal to function as a leaf node.
5. The apparatus of claim 3 , wherein the terminal is a first terminal and if the set role in the first terminal is changed from a leaf node into a supernode, the controller searches for a second terminal positioned next to the first terminal on a key space, and makes a request for reference information of a leaf terminal to the second terminal next to the first terminal.
In the apparatus described with the controller in claim 3, if a first terminal's role changes from leaf node to supernode, the controller searches for a second terminal that's adjacent to the first terminal in a defined key space. Then, the controller requests leaf terminal reference information from this adjacent terminal. This facilitates the first terminal taking on its new supernode role by acquiring necessary data from its neighbor.
6. A method of determining whether a set role of a terminal in a network is suitable based on capability of the terminal, by a super terminal or a leaf terminal, comprising: calculating, by an apparatus for setting the role, a capability value of the terminal; determining, by the apparatus for setting the role, without considering capabilities and roles of other terminals of the network, whether the set role set of the terminal, which is previously set, is suitable based on the calculated capability value; and managing, by the apparatus for setting the role, information regarding the set role in the terminal, wherein the previously set role of the terminal is previously set in the terminal, and wherein when the determining determines that the set role of the terminal is not suitable based on the calculated capability value, the terminal determines, without considering the capabilities and the roles of other terminals of the network, to change the set role.
A method, performed by a super terminal or a leaf terminal, for determining if its current role (super terminal or leaf terminal) is suitable based on its own capability without considering other terminals. The method involves: calculating a capability value for the terminal; autonomously determining, without considering other terminals, if the current, pre-existing role is suitable based on this capability value; and managing information about the terminal's role. If the role is deemed unsuitable, the terminal autonomously decides to change its role.
7. The method of claim 6 , wherein information used in the calculating the capability value includes network performance, remaining battery power, and usability of resource.
The method described previously uses network performance, remaining battery power, and resource availability/usability as inputs when calculating the capability value of the terminal. This capability value is the deciding factor when determining if the current super terminal or leaf terminal role is appropriate.
8. The method of claim 6 , further comprising performing a supernode role or a leaf node role based on the information regarding the set role of the terminal.
The method described in the sixth claim involves performing either a supernode role or a leaf node role, based on the terminal's role information. The determination of the appropriate role is dynamically determined based on the terminal's capacity and capability.
9. The method of claim 8 , wherein the terminal is a first terminal and the method of claim 8 further comprises, if the set role of the first terminal is changed from a supernode into a leaf node, searching for a second terminal; and transmitting reference information for a leaf terminal stored in the first terminal, to the second terminal.
In the method described previously, if a first terminal transitions from a supernode to a leaf node, the method further involves searching for a second terminal and transmitting leaf terminal reference information, stored in the first terminal, to the second terminal. This transfer ensures seamless network operation during role changes.
10. The method of claim 8 , wherein the terminal is a first terminal and the method of claim 8 further comprises, if the set role of the first terminal is changed from a leaf node into a supernode, searching for a second terminal positioned next to the first terminal on a key space; and making a request for reference information of a leaf terminal to the second terminal next to the first terminal.
In the method described previously, if a first terminal transitions from a leaf node to a supernode, the method further involves searching for a second terminal that's adjacent to the first terminal within a defined key space, and then requesting leaf terminal reference information from that neighboring terminal.
11. The apparatus of claim 4 , wherein the second terminal is a next super terminal.
In the apparatus described in claim 4, where the first terminal's role changes from supernode to leaf node and it transmits reference information to a second terminal, that second terminal is a "next super terminal". The "next super terminal" assumes responsibilities previously held by the first terminal.
12. The apparatus of claim 5 , wherein the second terminal is a super terminal.
In the apparatus described in claim 5, where a first terminal transitions from leaf node to supernode and requests information from a second terminal, the second terminal is a super terminal. This ensures the requesting terminal receives necessary data from a peer.
13. The method of claim 9 , wherein the second terminal is a next super terminal.
In the method described in claim 9, if a first terminal's role changes from supernode to leaf node and it transmits reference information to a second terminal, that second terminal is a "next super terminal". The "next super terminal" assumes responsibilities previously held by the first terminal.
14. The method of claim 10 , wherein the second terminal is a super terminal.
In the method described in claim 10, where a first terminal transitions from leaf node to supernode and requests information from a second terminal, the second terminal is a super terminal. This ensures the requesting terminal receives necessary data from a peer.
15. The apparatus of claim 3 , wherein the terminal is a first terminal and if the set role in the first terminal is changed from a supernode into a leaf node, the controller searches for a second supernode terminal positioned next to the first terminal on a key space, and transmits reference information, stored in the first terminal, for a leaf terminal between the first terminal and the second supernode terminal on the key space, to the second supernode terminal.
Building upon the apparatus described in claim 3 with a controller, if a first terminal changes from a supernode to a leaf node, the controller searches for a second *supernode* terminal that is positioned next to the first terminal on the key space. It then sends leaf terminal reference information (specifically, information relevant to leaf terminals located *between* the first and second supernode terminals on the key space) from the first terminal to the second supernode terminal.
16. The apparatus of claim 3 , wherein the terminal is a first terminal and if the set role in the first terminal is changed from a leaf node into a supernode, the controller searches for a second supernode terminal positioned next to the first terminal on a key space, and makes a request to the second supernode terminal for reference information of a leaf terminal between the first terminal and the second supernode terminal on the key space.
Building upon the apparatus described in claim 3 with a controller, if a first terminal changes from a leaf node to a supernode, the controller searches for a second *supernode* terminal that is positioned next to the first terminal on the key space. The controller *requests* reference information about leaf terminals located between the first terminal and the second supernode terminal on the key space from the second supernode terminal.
17. The method of claim 6 , wherein each terminal of the network determines, without considering capabilities and roles of other terminals of the network, its own set role.
In the method described in claim 6, each terminal in the network independently determines its suitability for its current role (super terminal or leaf terminal) without considering the capabilities or roles of any other terminals in the network. Role determination is solely based on a terminal's own assessment of its capabilities.
